Guys... ... . Is anyone reporting any "ruff clutch pedal feel" on 2004 4X4 6spds? Seems to be getting worse but is intermitent 15K miles on truck. Could be effected by water as problem is worse after driving through heavy rain conditions. Dealer has changed out the hyd master/slave unit but no improvement. Condition exists only when engine is running. Clutch reaease mech???????
